Defective in Lipophosphoglycan Biosynthesis Interferes With Activation of Human Neutrophils.

Visceral leishmaniasis (VL) is often associated with hematologic manifestations that may interfere with neutrophil response. Lipophosphoglycan (LPG) is a major molecule on the surface of promastigotes, which has been associated with several aspects of the parasite-vector-host interplay. Here, we investigated how LPG from (.

Deciphering the Role Played by Autophagy in Infection.

In recent decades, studies have shown that, depending on parasite species and host background, autophagy can either favor infection or promote parasite clearance. To date, relatively few studies have attempted to assess the role played by autophagy in infection. While it has been consistently shown that spp.

A docking-based structural analysis of geldanamycin-derived inhibitor binding to human or Leishmania Hsp90.

Leishmaniasis is a neglected disease that affects millions of individuals around the world. Regardless of clinical form, treatment is based primarily on the use of pentavalent antimonials. However, such treatments are prolonged and present intense side effects, which lead to patient abandonment in many cases.

In vitro evaluation of the anti-leishmanial activity and toxicity of PK11195.

Background: Leishmaniasis, one of the most neglected diseases, is a serious public health problem in many countries, including Brazil. Currently available treatments require long-term use and have serious side effects, necessitating the development of new therapeutic interventions. Because translocator protein (TSPO) levels are reduced in Leishmania amazonensis-infected cells and because this protein participates in apoptosis and immunomodulation, TSPO represents a potential target for Leishmania chemotherapy.
